Actuated 3 way Ball Valve
Selection Guide

About 3-way Ball Valves

Three way ball valves have 3 ports. They are available in a variety of body materials and with all of the common end connections. They can be manually operated or automated with an electric or pneumatic actuator. They can be used as diverter valves, where flow a single inlet is diverted to either of the two other ports as the outlet. They can also be used as an input selector where a single outlet port is fed the flow from one of the other two ports as the supply inlet. The bore through the ball (ball drilling) comes in two varieties, "L" and "T" as shown below.
